By means of hydraulically and/or pneumatically applied force, divided over the surface of the tubular member by means of at least one flexible pressure applying means arranged surrounding the tubular member, said member is thereafter given a conical shape corresponding to the shape of the core, the reduction in diameter of the member being compensated for by means of a change in the shape of the profilings .
